Re: Engine revs rising when air lever opened

Thanks for your replies. The carb is a 930, not sure of the jet sizes, but can check later. Magdyno ignition. I cannot see any movement of the main slide when the choke is opened or closed. There is no air filter so easy to check. As I mentioned it was starting and idling OK a few months back. Drop...

Re: Engine revs rising when air lever opened

It might be obvious ... When the air lever is "closed", it "drops" a little slide into the mouth of the carburettor, to choke it. When you "open" the air lever, it raises the little slide. This little slide isn't getting caught and raising the main slide at the same tim...

Re: kh engine rattle

One of my singles "pinks" , if I have it fully advanced and am not flat out.

Re: kh oil pressure

You need a T-piece in the return line - in/out and up to the rockers
The gauge is fed directly from take-off on the crankcase
One of the ends on the rocker feed spider needs blanking.
use flexi pipe as it's much much more user friendly

Re: kh oil pressure

I do not pressure feed the rockers either, that is done from the return line. My gauge is around 50-80 at speed, depending on temperature, and is directly attached to the original oil take off for the rockers. I had an awful time with pressure readings (zero) and over-oiling at the top end, before I...
